2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
x3 + 2x2 + 3x + 6 = x2(x + 2) + 3(x + 2) = (x + 2)(x2 + 3)
2(x^2 +2x + 3)
(x + 2)(x^2+4)

2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
x3 - 2x2 + x - 2 =(x - 2)(x2 + 1)
x3 + 2x2 + 3x + 6 = x2(x + 2) + 3(x + 2) = (x + 2)(x2 + 3)
whats the answer for -2x^3+2^2+12x
2(x^2 +2x + 3)
2 x 2 = 4 and you will know that byyyyy counting 2 plus 2 and that give you 4 and you can do 2,4,6,8,10
(x + 2)(x^2+4)
4 + 4 = 8.Get it?You multiple the number 2 times and then you add 2.It's very confusing.
x2 plus 6x-2 equal -2x2 plus x ..=7x equal -3x2 ..4x=2x=2 answer ..check it if u dont want to trust ..Improved Answer:x2+6x-2 = -2x2+xx2+2x2+6x-x-2 = 03x2+5x-2 = 0(3x-1)(x+2) = 0x = 1/3 or x = -2The answer can be checked by using the quadratic equation formula.
2x2=4x4=16
2x2 + 9x + 10
